7 CENTRAL-DRAFT LAMP.

SPECIFICATION forming part of Letters Patent No. 408,135, dated July 30, 1889.

Application filed February 4, 1889- Serial No. 298,609. (No model.)

To all whom, it may concern: and serves as a support for the chimney. The Be it known that I, EUGENE H. PEOK, of representation of these parts is all. that is Meriden, in the county of New Haven and necessary for the full illustration of the in- State of Connecticut, have invented a new vcntion.

Improvementsin Central-Draft Lamps; and I Upon the outer tube A a metal sleeve E is do hereby declare the following, when taken arranged so as to slide freely up and down in connection with the accompanying drawthereon. Its length is such that when in the ings and the letters of reference marked theredown position its upper end will come below on, to be a full, clear, and exact description the upper end of the tube Athat is, below 10 of the same, and which said drawings constithe exposed end of the wick. A lever F is tute part of this specification, and represent, arranged in the shell or base of the burner, inand extending outside forms a handle by Figure 1,a vertical central section showing which the lever maybe operated. The inner the wicktube and extinguisher in half side end of the lever is hung to the sleeveE (here I 5 View, with the extinguisher in the down porepresented. as forked) and so as to be pivsition; Fig. 2, the same as Fig. 1,with the exoted to the sleeve upon opposite sides, as tinguisher in the up position; Fig. 3, a top more clearly seen in Fig. 3. The sleeve E is view in the closed position; Fig. 4c, a modifimade from elastic metal, and it is slit from its cation. upper end downward, the slits preferably be- 20 This invention relates to an. improvement ing vertical. a represents these slits. By in that class of lamps in which the wick is of slitting the sleeve in this manner a series of tubular shape, arranged around a tube, and springs G are formed around the tube A. through which tubeair is supplied to the in- Near the upper end these springs are bent inside of the flame to aid in the support of comward, as at I), and so that as the tip of the 25 bustion, commonly called central draft spring rests against the tube A the bend will lamps, the object of the invention being to be forced from the tube; but the tendency of provide a device for extinguishing the flame the springs is to bring the part of the spring withoutthenecessity of moving the wick; and below the bend flat against the tube A, as the invention consists in a sleeve arranged seen in Fig. 2.

Then when the sleeve is 45 flame. again drawn down the tips of the springs A represents the outer tube of a centralwork over the upper end of the tube A as draft burner, and B the inner or central tube cams to force the tips outward onto the sleeve, of the lamp, between which the wick C is aras seen. in Fig. 1. This simple extinguisher ranged in the usual manner; D, the shell of is most effective in its operation, adds but a 50 the burner, which surrounds the outer tube trifling cost to thelamp, and avoids the neces- IOO sity of forcing the Wick downward, or the common but dangerous practice of blowing down the chimney to extinguish the flame.

The lever F is the best device for operating the sleeve E 5 but it will be understood thatv it may be otherwise operatedas, for instance, by a handle rigidly fixed thereto, and so as to extend through a vertical slot in the shell of the burner, as seen in Fig. 4.

'VVhile the springs are best made by the formation of a sleeve and slitting it vertically, the sleeve may be made by attaching vertical springs of the requisite shape to a ring, as seen in Fig. 4:. I therefore do not wish to limit the invention to the necessity of making the sprin gs integral with each other and the ring or body which carries them; but

What I do claim is 1. 111 a central-draft lamp, a sleeve arranged upon the tube which surrounds the wick and so as to slide vertically thereon, the upper end of the said sleeve forming a series of vertical sprin s around the tube, their upper ends bent inward, so that when the sleeve is raised the upper ends of the springs will close inward around and above the upper end of the wick, and on the descent of the sleeve the said springs will spread and pass onto the outside of the tube, substantially as described.

2. The herein-described extinguisher for central-draft lamps, consisting of a sleeve E arranged upon the outside of the tube and so as to move vertically thereon, the upper end of the said sleeve slit to form a series of vertical springs integral with the sleeve, the upper ends of the springs bent inward, so as to close over the Wick when the sleeve is raised, and a lever hung to the sleeve and eX- tending through the burner, substantially as described.
